To all whom it may concern: 7

Be it known that 1, JOHN 'W. CAMPBELL, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and

- State of Pennsylvania, have invented a new and useful Improvement in Convertible Beds and Sofas, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which forma part of this specification.

. My invention has for its object to provide a structure comprising movable parts so constructed that the structure may be readily converted from a sofa to a bed or vice versa and to accomplish this result by mechanism that will be actuated by the simple act of depressingor lifting the frame of the strucspecific plates removed and part of l on the casters 'ture forming the back of the sofa.

The invention also has for its object to provide mechanism that will operate smoothly and with certainty and that will be simple and durable.

The invention consists of the general and construction and arrangement of parts hereinafter described and particularly claimed.

I In the drawings: Figure 1 is a side view of the structure when converted-into a sofa. Fig; 2 is a front view of the same.

is a side view of the same, with the side the arm rest in 4 is a side view similar to section. Fig.

Fig. 3 except that-the parts haveheen folded to form-a bed.

The main parts of the structure, exclusive of the interconnecting operating. mechanism, comprise: first, the central frame or main body including the base pieces a, supported I), and'the box-frame d supported on the base pieces a; second, the seat 0 supported on the box-frame d; third, the pivbtally mounted back frame 6; fourth, the pivoted front frame f; fifth, the side plates (1 secured to the box-frame d; sixth, the arm set. 23, u, pivotally connected to thecentral am. back frames; fram r'p, comprising a headboard and legs and pivoted to' the back-frame.

supported on the sidesor-ends of the'main 5t body and inside the side plates g, which the slot of gages a pm we on the fr Fig. 3'

The means- .by'which the front and back frames are supswiriging the frameserve to conceal such mechanism. The said mechanism is duplicated at opposite sides or ends ifof ahe main body, and the descriptionof one setiof this mechanism will suffice; In

When the seat is thus pulled forwardly, it may be swung upwardly and b ackwardly on the plates 0? as a, pivot, thus enabling the back frame 0 to be swung forwardly in converting the contrivance from a bed to a sofa, and also permitting access to be had to the interior of the box-frame (2.

Having now fully described my invention, what I claim and desire to protect by Letters Patent is z- 1.
